Infoday ANSA/LS-OPT/META

Both in LS-OPT as well as in ANSA and META (BETA CAE Systems) there are interfaces for easy coupling between these programs.

ANSA offers excellent possibilities for parameterized modifications of FE meshs using morphing
technologies. The control parameters for morphing are passed to LS-OPT and modified and controlled there. Due to this, form optimizations or robustness analyses taking into account geometrical changes can be implemented very easily. In addition to this, any optimization variables desired can be defined in the FE input files in ANSA and be passed to the optimization process in LS-OPT.

Furthermore, META can be used to extract simulation results, which can then be automatically imported by LS-OPT. This is of particular interest if FE solvers other than LS-DYNA are used for optimization.

This information day shows how ANSA and META can be used together with LS-OPT for optimization and stochastic analyses. This is underpinned by examples from industrial practice.
